.Sh NAME
.Nm uslcom
.Nd Silicon Laboratories CP2101/CP2102/CP2103/CP2104/CP2105 based USB serial adapter
.Sh SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Bd -ragged -offset indent
.Cd "device usb"
.Cd "device ucom"
.Cd "device uslcom"
.Ed
.Pp
Alternatively, to load the driver as a
module at boot time, place the following line in
.Xr loader.conf 5 :
.Bd -literal -offset indent
uslcom_load="YES"
.Ed
.Sh DESCRIPTION
The
.Nm
driver supports Silicon Laboratories CP2101/CP2102/CP2103/CP2104/CP2105
based USB serial adapters.
.Pp
The datasheets for the CP2101/CP2102/CP2103 list the maximum
supported baud rate as 921,600.
Empirical testing has shown that the rates 1,228,800 and 1,843,200 also work,
at least on some hardware, so the driver allows setting those rates.
